Whether they make you fat, fart, or freak out, microbes play a central role in your life. Right beneath your nose—on your face, in your gut, and everywhere in between—trillions of bacteria, viruses, and fungi are so abundant in your body, they outnumber your human cells. But these aren’t just nasty hitch-hikers. Many are crucial to your survival. Evidence suggests that a diverse microbiome can keep you healthy and, conversely, a damaged one could kill you. NOVA Wonders peers into this microscopic world to discover the fascinating, bizarre, and downright surprising secrets of the human microbiome, including the world’s largest stool bank, which transforms raw stool into life-saving poop pills.

What's Living in You?

Whether they make you fat, fart, or freak out, microbes play a central role in your life.

Are We Alone?

Artificial intelligence is examined. Included: the effort to build intelligent machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power.

Can We Build a Brain?

Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches…the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence? The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. NOVA Wonders looks at how far we’ve come and where machines are headed as their software becomes ever more…cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?

Can We Make Life?

"It's alive!" Since Dr. Frankenstein spoke those famous words, we've been alternately enthralled and terrified by the idea of creating life in the lab. Now, a revolution in genetic engineering and thrilling innovations in synthetic biology are bringing that dream—or nightmare, as the case may be—closer to reality. New tools allow researchers to use cells to create their own DNA and edit it into existing genomes with more ease and less cost than ever before. Along with renewed hopes for treating some genetic diseases, there's serious talk of using the newest technologies to bring long-extinct animals back from the dead – like the team hoping to resurrect the woolly mammoth. Science fiction is quickly becoming science fact. NOVA Wonders explores the benefits and the burden of risk surrounding the controversial new technology

What's the Universe Made Of?

The universe is hiding something. In fact, it is hiding a lot. Everything we experience on Earth, the stars and galaxies we see in the cosmos—all the “normal” matter and energy that we understand—make up only 5% of the known universe. The other 95% is made up of two mysterious components: “dark matter” and “dark energy.” We can’t see them, but we know they’re there. And what’s more—these two shadowy ingredients are locked in an epic battle to control the very fate of the universe. Now, scientists are trying to shed light on the so-called “dark sector” as the latest generation of detectors rev up, and powerful telescopes peer deeper into space than ever before to observe how it behaves. Will the discoveries help reveal how galaxies formed? In the series finale, NOVA Wonders journeys to the stars and back to investigate what we know—and don’t know. Find out how scientists are discovering new secrets about the history of the universe, and why they’re predicting a shocking future.

How Safe is Meat?

An English breakfast, bangers and mash, a bacon butty, and the traditional Sunday roast: dishes synonymous with the great British cuisine. But when the World Health Organisation (WHO) recently said that eating processed meat can cause bowel cancer, and red meat probably causes cancer, many people became concerned that their favourite dinners could be harmful to their health. Tonight How Safe is Meat? Examines the evidence behind the WHO’s announcement, and puts the risks of eating meat in context. Reporter Fiona Foster speaks to leading scientists, medical professionals and representatives of the meat industry to find out: do you really need to bin your bacon buttie?

Coffee and Tea

Gloria and Chris settle the argument over whether tea and coffee are good or bad for us - and if the same is true for both. There is also the truth about a food often touted as a way to fight cancer. And, after reports suggesting reusing plastic water bottles is a bad idea, tests reveal if we should be using a fresh one every time.

Part 2

The series offers a fresh look at the science behind teeth and dentistry, and what we can all do to improve our oral health. The programmes feature patients undergoing treatment for missing or broken teeth, decay, gum disease, and a range of other problems – sometimes to the extreme. The series also features a strong public health message, with experiments on and information about everything from correct tooth brushing to the effectiveness (or otherwise) of over-the-counter tooth whitening kits.
